I don't question the potential of the therapy but as with any therapy it is not generally proven until it is done in a double blinded clinical trial. So far all results are based on testimony of individuals and report from company. Take the case of Chinese herbal medicine for example. Historical data over many years but is not accepted by general medical professionals. I am a bit surprised that it is not required for stem cell therapy to obtain phase iii trial double blinded study data before being allowed to market it commercially as required in all other new drugs. Just my opinion.
